Hey @intrepidsurfer, are you still planting trees? Because if so I nominate your tree planting! :)
There is also @treeplanter, and off blockchain, if you accept non-blockchain projects, I nominate One Tree Planted http://onetreeplanted.refr.cc/wrenpaasch (that is my referral link which will give you a code to plant one free tree. You copy the code, choose a project, and then paste it into the discount box at checkout, and it will subtract a dollar. The trees are a dollar each, and you can buy one at a time, so, free).
